ceases.

'lo all whom it may concern:

3e it known that I, PAUL HANNAGAN, a citizen of the United States, residing at Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Snow-Flows, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention comprises various improvements in snow plows for use in removing snow from side-walks, gutters, and roadways, or in spreading and leveling it over roadways.

In the drawings,Figure 1 shows in sideelevation a snow-plow embodying certain of the present improvements. Fig. 2 is a plan thereof. Fig. 3 is a plan of a snow-plow of modified construction. Fig. 4: is a side elevation of a plow of further modified construction. Fig. 5 is a plan thereof. Fig. (5 is a plan of a plow having a mold-board arranged to swing vertically. Fig. 7 is a rear elevation thereof.

The frame of each of the plows herein shown and described. resembles in character that of the plow of United States Letters Patent No. 855,886, granted to me under date of June 1907. In the case of the plow shown in Figs. 1 and 2, the frame comprises the opposite side-bars 1, 1*, upper cross-bars 2, 2, extending from one sidebar to the other, runners 3, one or more side stanchions 4 extending down from a sidebar to a runner, a lower cross-bar 2*, rear stanchions 5, 5, extending down from the rear ends of the side-bars to the rear ends of the runners, front stanchions 6 constituting cutters and inclining downward and rearward from the front ends of the side-bars to the front ends of the runners, and a crossbar 7 extending from one cutter to the other. The specific construction may vary. Atthe side of the frame at which the snow discharges from the mold-boards the space between the side-bar and the runner is open so as to permit free lateral escape of the snow as it is crowded sidewise and slides along the mold-boards. At the opposite side of the frame the space at the rear of the side stanchion 4c is closed by a sheet 8, preferably of iron or steel. Sidewise displacement of the plow in consequence of the resistance offered to the transversely inclined mold-boards by snow packed in front of the latter is opposed by the snow alongside the Specification of Letters Patent.

Application filed April 25, 1910.

Patented July 5, 1910. Serial No. 557,327.

outer surface of the said side-sheet 8, so that lateral divergence of the plow is avoided and the plow enabled to travel along in a straight path. The said plow of Figs. 1 and 2, and the other plows herein shown, are intended to be drawn by horses hitched thereto, as in the case of the plow of the Letters Patent aforesaid, but the propelling power may be varied.

The plow of Figs. 1 and 2 is provided with mold-boards or scrapers A and B, and a mold-board or leveler C. The mold-board or scraper A, when in its working position, extends obliquely across the frame of the plow at the rear of the cutters 6. It is of a length sufficient to cause its extremities to project through openings of the opposite side-frames of the plow, and some distance outward beyond the said side-frames at both sides of the plow. It is mounted in advance of the others, and will remove the snow from a path of a width beginning at a point some distance outward from the side-bar 1 and corresponding runner, and extending transversely to a point at some distance outward from the side-bar 1 and corresponding runner, the snow being discharged at the latter side. The shorter mold-board or scraper B, at the rear of mold-board or scraper A, when in its work ing position extends obliquely across the plow in the same general direction as moldboard or scraper A, and it discharges the snow toward the same side of the plow as the latter. The third mold-board, or leveler, G, is hung or pivoted by one end thereof at the point 0 to the frame of the plow at the same side of the latter as that on which the mold-board or s *raper B, is hung or pivoted. Its purpose is to level off the ridge of snow produced by the action of the second moldboard or scraper B, reducing such ridge in height.

Mold-board or scraper A, when in its working position rests at its rear side against and is backed up by a side standard at near tating the rods a, a, as by taking hold of the hand-wheels a aflwhich are fixed upon the .said rods, the mold-board or scraper A is raised or lowered as required. One of the screw-threaded rods a, a, is supported in bearings upon the plow-frame at the side of the plow-frame at which the rear end of 'inold-board or scraper A is located. The

other is supported bya bearing 0; which is mounted .as presently will be described. Not-ches a a are formed in the lower edge of the molchboard or scraper A to receive the runners 3 and thereby enable the said mold-board or scraper to be lowered all the I tion it will scrape clean the surface over" way down. hen'it is in its bottom posiwhich the plow is drawn. In a higher p0,-

sition'it will scrape off the top portion of the snow to the eXtentdesired, and it may be utilized for removing a topcrust. It may be used in its higherposition to decrease the depth of the snow so, as to lessen the work devolving upon the second nold-board or scraper B in clearing a side-walk or gutter.

To avoid having to turn the plow out of its proper path in order to clear a tree or other: obstruction standing in the Way of the projecting leading end of the moldboard, or scraper A, the bearing a for the adjacent screw-threaded rod a is mounted in curved gu de of, Fig. 2, 6Xl361'id111g t19108s the top' of the frame of the plow, the bearing being movable along this guideway so that the mold-board or scraper A'may be swung transversely inclined or oblique position shown in Figs. 1 and 2 to an intermediate position inwhich its leading end is between the sides of the frame, or even to a position in which the entire length of the said mold board or scraper is located closeto'the opposite side of the frame. This mode of mounting the said mold-board or scraper enables it, when elevated sufficiently by means of screw-threaded rods a, a, to clear the run- 11ers 3, to be swung inwardlytoward the middle of the width of the plow clear of any obstruction, tree, or the like, without changing the course of the plow itself, and consequently without diverting the moldboard or scraper B from the required path upon the side-walk or in the gutter. The

mold-board or scraper A may be secured in,

either of the positionslast described, as desired,jby means of a hook A engaging with i a hole int-he. cross-bar 7, as shown by dotted lines in Fig; 1, or with. the side-frame of which side-bar 1" forms a part. The side of the plow-frame beyond which the leading end of the mold-board or scraper A projects V being open or-skeleton like as indicated in Fig. 1,.at least in the fore-part of the plow,

" the l-eading end of the said mold-board or scraper freeto swing transversely in and out through the said side. The'lateral extension of mold-board or scraper enables the horses by which the plow is propelled to be kept out of deep snow that has been 'shoveled into a gutter, in case the plow is being used for leveling off the deepsnow preliminary to cleaning out the gutter. This advantage grows'out of thefact that pying holes; in the intermediate cross-bar 2 and in-a lug (not shown) projecting from a suitable. portion of the side-frame below said cross-bar.

engagednwith an upright pin or rod 1) occu- Toenable the .width of the path cleared bythe mold-board or scraper B to be varied as required, the said mold-board or scraper is mounted with capacity to be swung transversely more or less'upon its pivot b. It is held in the desired position of adjustment by means of the pin 7),, which is inserted in a vertical position into holes b 5 in upper and lower transversely extending braces 12*, 6 extending across the frame from one side thereof to the other side thereof. around the other rod or as a pivot from its j Toprevent the free or swinging rear end of mold-board or scraper B from dragging,

it is engaged with a horizontal strip or bar forming a part of the plow-frame.

strip or bar is in the case of Figs. l and 2 the lower cross-brace 6 which extends from the rearend stanchion at one side of the plow-frame to the rear end stanchion at the mold-board or scraper is slotted as at b", Fig. 1, to fit the same. Thereby the said end is supported in the different positions of the mold-board or scraper B.

This

,other side thereof.v For engagement withthe said strip or bar, the said end of the When in its working position the moldboard or leveler .C occupies a rearwardly inclined position shown in Figs. 1 and 2, in

which it is retained by means of a link 0 having one end thereof engaged, as by means--- of a hook, with, side-bar .11 of the frame, as

by means of a hole or eye at c in the rear end of such. side-bar into which the said hook enters, the said link having the other end thereof similarly engaged, as by means of a hook and an eye 0 with a convenient portion of the mold-board or leveler C. The

forward end of link 0 might be engaged in one of the holes 11 of upper cross-brace b.

To enable the transverse obliquity or in-- clination of the mold-board or leveler C to be varied, the forward end of the link 0 may be shifted into any suitable one of the holes 6 of the upper cross-brace 12 When it is desired to put the three moldboards, or scrapers, and leveler out of operation at the time when the plow is being moved about from place to place, the moldboard A is swung as already referred to, from its position in Figs. 1 and 2 into a position close alongside the opposite side of the plow-frame, and held in such position by the hook A engaged in a hole in sidebar 1 The mold-board or scraper B is released by withdrawing the pin 6, and swung up close against the first side of the frame, and there secured by a pin introduced into holes of rear cross-bars or braces 2, 2, or in braces or cross-bars b 6 The third mold-board or leveler C either may be removed by disengaging the link 0 and disconnecting the said mold-board or leveler from the pivotal pin 0, or the link 0 may be disengaged and the mold-board or leveler C may be swung around and forward against either the outer side or the inner side of the side of the plow-frame to which it is pivotally connected, and be there secured snugly in place by suitable means.

In the case of the plow shown in Fig. 8 the first mold-board or scraper A is-made in two parts, respectively designated a and a, the former of which is pivoted at a and the latter at a the pivots being located at the opposite sides of the plow-frame. When in its working position the portion a of the said mold-board or scraper rests by its leading extremity against the front edge of the side-stanchion 4: adjacent the pin a to which the portion a is pivoted, and the inner extremity of the said portion a nor mally occupies a position overlapping and in contact with the portion a. The outer extremity of the portion a is engaged by the hooked outer end of a link a which enters an eyepiece a connected with the said outer end, the said link a having at its inner extremity engagement with an eyepiece a carried by the fore-part of the corresponding side of the plow-frame. WVhen it is desired to render the two-part moldboard or scraper A inoperative, the link a is disconnected from the portion a and the latter is swung upon its pivot a so as to carry the outer part of the said portion around rearwardly against the outer surface of the corresponding side of the plow-frame, while the inner part of the said portion is swung forwardly around close up against the inner surface of the said side of the plow-frame. Also, the portion a is swung upon its pivot a so as to cause it to lie close alongside the other side of the plowframe. The portions a a", are held in convenient manner in the positions described. Mold-board or scraper B and its attendant features are substantially as in the case of the corresponding part and features of Figs. 1 and 2, and this mold-board or scraper may be caused to assume an inoperative position alongside one side-frame of the plow-frame, as already explained, by removing the holding-pin Z). The mold-board or leveler C of Figs. 1 and 2 is omitted from Fig. 3, but may be employed if desired. The construction shown in Fig. 3 is advantageous because the leading end of the said moldboard or scraper may be caused to project more than in Figs. 1 and 2.

Then the plow is at work with moldboard or scraper B in use, the snow scraped up thereby is permitted freer escape at the discharging side of the plow, in Figs. 1, 2, 3, by the fact that the side-frame and runner are shorter at that side than at the other. By having the rear-stanchion at the discharging side set farther forward, it is out of the way of the rear end of mold-board or scraper B, permitting the said mold-board or scraper to be adjusted around farther than otherwise would be possible thus enabling a wide path to be cleared when the occasio-n demands.

The plow of Figs. f and 5 employs in ad dition to mold-board or scraper B, and mold board or leveler C, a two part mold-board or scraper a a, like that of Fig. 3, and above the same a second mold-board or scraper D which is pivoted near one end thereof upon the pin (Z located close alongside the pivot-pin b of the mold-board or scraper B, the opposite end of the moldboard D being held up to its work by a removable backing-pin 0Z applied to upper and lower horizontal strips or braces Z)", Z), Y

at the corresponding side of the plow-frame. The said opposite end of portion a rests upon and is supported by the lower one of the said strips or braces b which constitute a track therefor. The two strips or braces 6 I), are attached at their front ends to a side-stanchion 4 and at their rear ends to the rearmost cross-braces, 2, 2*.

The lower two-part mold-board a a, of Figs. 4 and 5 is alone needed for working after a light snow-storm. The upper front mold-board D comes into service when con.- siderable snow has fallen. In operating to clear gutters into which considerable snow has been shoveled, causing the accumulation to be more than mold-board or scraper B can handle, the upper front mold-board D is used, the twopart front mold-board a a", being thrown out of use by swinging its two sections into their inoperative or non-working positions. On occasion, the upper front mold-board D alone may be utilized in first going over the course, the mold-boards a a, B, C, being put out of action, and in making a second run over such course the mold boards B and G being brought into action. Mold-board D may be adjusted into different" working positions by tshifting; pin d I such mold-board over toward the side where it is hungfor pivoted.

Figs. 6 and 7 show a construction in which a mold-board or scraper corresponding substantially with the second mold-board or scraper B of the preceding figures, here lettered B, may be swung vertically from its working position in Figs. 6 and 7 into a I position immediately below the cross-bars 2, 2, 2, at the top of the plow-frame. I The mold-board or scraper B is hung by means of straps b b from a'Jsupporti-ng rod 6 occupying a horizontal' position immediately below the cross-bars, andheld by supports b which are attachedto the saidcross-bars.

The rod 6 occupies a transversely oblique position corresponding with the oblique position necessary to be occupied by mold-board V or scraper B" when at work. When the mold-board or scraper occupies its working position, it is backed-up by a backing piece I) which is connected with theplow-frame,

. and it is locked in such position by means of a swinging latch I)" pivoted to one of the straps Watt and adapted to engage with the backing-piece 6 When'the latch 6 islmoved so as to disengage'itfrom the backing-piece Z1 thereby releasing the said mold-board or scraper, the latter may be swung around the axis of the rod 12 up against'or near the cross-bars, where it maybe suitably held, as by means of a hook, I).

In some instances the plow may be mounted upon wheels, instead of runners.
